carl883August 1, 2011

Should I get a single stage or a dual stage. The contractor

is saying a XLI15 heat pump will do the job,But I dont want

tempature varation in the house. The XLI16 is a dual stage

is it more economicial ???

What size are you looking at?

I think a two stg is more about comfort than operating cost savings. You need to weigh cost differences and a reasonable payback period. I have found that it can be difficult to justify from a monetary standpoint.
